摘要

A simple and efficient synthetic route to the bicyclic α, β-unsaturated β-keto ester methyl (3aS, 7aS)-6-oxo-2, 3, 3a, 6, 7, 7a-hexahydro-1H-indene-5-carboxylate, a versatile intermediate in the synthesis of biologically active unsaturated 1, 4-dialdehydes, is described. The synthesis includes a chirality introducing nonenzymatic asymmetric desymmetrization (ADS) reaction of a cyclic meso-anhydride 4 and a modified Hofmann ...
